Its story

17 Persei is a swollen, mature K5 orange giant burning at around 4,000 K —considerably cooler than the Sun— and resting 467 light-years away, in the mythic torso of the hero Perseus. Its amber light travels for sixteen human generations before reaching an observer's eye on Earth. Modest to the unaided eye, its warm hue still sets it apart from the brilliant blue-white stars that crowd the constellation.
